How to generate a 4096-bit RSA key with your invitation code
Your FuZeFACTORY invitation code doubles as the passphrase for your RSA key. This keeps your key material
bound to something only you and our onboarding system know, and helps prevent man-in-the-middle attacks.
macOS / Linux
- Open a terminal.
- Run:
ssh-keygen -t rsa -b 4096 -C "FuZeCLOUD"
- When prompted for a passphrase, paste your FuZeFACTORY invitation code exactly.
- By default this creates a private key file (for example
id_rsa) and a public key file
(for example id_rsa.pub) in ~/.ssh.
- Open the
.pub file in a text editor and paste its full contents into the
“RSA public key” box above.
Windows (PowerShell / OpenSSH)
- Open PowerShell.
- Run the same command:
ssh-keygen -t rsa -b 4096 -C "FuZeCLOUD"
- Use your FuZeFACTORY invitation code as the passphrase when prompted.
- Locate the generated
id_rsa.pub file (usually under C:\Users\<you>\.ssh),
open it, and paste the contents into the public key field above.
Keep your private key and invitation-code passphrase secret. We never ask for either — only the public key.
